invert a 3x3 matrix in python

main.py
import numpy as np

# define your 3x3 matrix as a numpy array
matrix = np.array([[1, 2, 3],
                   [4, 5, 6],
                   [7, 8, 9]])

# invert the matrix using the inv() function
inverse_matrix = np.linalg.inv(matrix)

# print the result
print(inverse_matrix)
